Be it hown that I, Perm nor a citizen of the United States, residing at yracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Pressure Compensators for Presses, of which the following is a specification,

This invention relates to presses and hndred machinery, and more particularly to an improved pressure compensator for garment presses,

Among the several objects of this invention, a primary one is to produce a pressure compensating device used in connection with all types of garment pressing machinery for. transmitting an even, firm yet slightly yieldable pressure from the prune mover to the part moved as for example the press head working against the garment on the buck Some garment presses are subjected to usages of a varying nature and in fact rough when. pressing garments of various usa e thhkesses and when worked by inexperienced operators The device constituting (this invention establishes uniform and even trates a side elevation of a typical garment press embodying a pressure compensator.

Figure 2 illustrates a'longitudimil sectional view of the pressure compensaton.

Referring still further to the drawings for I a more complete description ofthe invenlever 5. The frame suppo tionythere is shown a ress frame 4, on the upper part of which is fulcrumed apress rts the usual garment su buck 6, and the lever 5 carries the usu pres' head 7, either or both of which are provi ed with steam for heating and treating p as is known to those conversant with 0 art.

A foot lever 9 is pivoted in the lower portion of the flame and connects through.

a link 10 with a toggle comprisin the pivotally joined parts 11 and 12. e-toggle 11-12 has one end thereof pivotally conota able or movable one upon the other.

nected with the press frame, and the other end is connectedto the lower part ll of the toggle l4l5. This vertical toggle ill- 15 is pivotally connected to the hackpnd of the 1Lpress lever 5 and has its'lower end pivy supported on the pin. 16 which may be either fixed to the press frame or to a power part 17 as the case may he The press lever 5 and ressing head 7- actuated by manually epress' the foot lever 9,and a spring 19 is amac ed to the toggle ld 15 and to the framelto normally ho d the vertical toggle in a broken position so asto' restrain the press head 7 in open position in order that a garment may he quickly placed on the buck 8 and made readyfor pressing,

The foregoing description covers generally the organization of some of the machine parts employed in a typical garment pres, and the present invention has to do v more particularly with one member or part 15 ot the main press toggle ld-l5, which has been above referred to as a compensator, a description of which will now be given: p v

A spring cup or base ,l5'is provided with depending spaced parallel ears 24 with a hole therethru providing for a pin 25 to attach the lower end of the compensator device to the upper epd of the toggle part 14. 'The spring cup is flanged as pointed out at 26 and a threaded bore 27 made centrally through this base part.

The larger end 27 of an stem is threaded and screwed into the base 15. A heavy spring 28 rests and is confinednin position by the flange 26,

A spring cap'29 1s placed'on topof the r' 28. A ressui-e block 31 is made with an integra sleeve 32 and rests upon the spring cap 29 with the sleeve 32 projecting downwardly part Way through the spring 28. The pressure block 31 has an openin made therethrough for the reception 0 the u per. smaller end 33 of the adjusting stem w ch renders the stem and pressure block adjust- The pressure block has a hole 37 for the rece tion of a pin 38 employed in assembling t e com nsator device withinthe press lever 5.

pressure hock 31 and has an adjusting nut fixedtothestembytaperpinsorother' against the base 15- I.

ad'usting stem projects from the suitable means so that a wrench may be ap-- plied to the nut to turn the screw 27 to screw this part farther into the base 15. Several adjusting screws 36 are screwed into the pressure block31 and engage the face of the spring cap. These adjusting screws 36, preferably about three in number, are equi-distantly disposed about the stem 33 so as to uniformly transmit the pressure delivered from the spring to the, pressure block. I

When the pressure compensator 15 is installed within the press lever 5 and has its lever end attached to the toggle part 14, as hereinbefore described, why'then, the pres sure compensator itself acting with the part 14 constitutes the main toggle of the press;

and when the foot lever or pedal 9 is thrust downwardly the toggle 14-15 straightens to jam the head 7 against the buck 6. 'In executing this pressing action, the lateral force developed ilr the toggle '1112 straightens the vertical toggle 1415,.whereupon the thrust is translated into a vertical force exerted through the straightened vertical toggle, and against the back end of the press lever 5. r

The force working against the press lever to close the head 7 is transmitted from the base, 15 through the spring 28 to the spring cap 29 and then through the adjusting screws 36 to the pressure block 31 and finally delivered'against the press lever 5. Now in case the toggle part 15 was of the rigid or non-yielding type, there would be considerable danger of breaking some part of the press. But by employing the yieldable yet very stiff and firm spring 28, the'danger of breakages is eliminated without impairing the pressing capabilities of the machine.

At times a press is put to unusual hard tasks in pressing very thick and heavy goods and in such; cases the distance between the points 38 and 16 on the press must be adjusted or shortened up so that the vertical toggle will straighten by, the time the head closes on the garment. This is accomplished by rotating thc'stem 27 to draw the pressure block and base closely together; and when this adjustment is made it is usually practical to loosen up on the spring 28 by unscrewing the adjusting screws 36 to relieve slightly the increased pressure of spring 28. Again it is often necessary to slightly. vary the pressure between the pressing elements 6 and 7 in the treatment of various kinds of fabrics; and less pressure or more pres sure as desired, may be obtained by the proper adjustment of the screws 36 to vary the compression of the spring 28.

Havingthus described the construction and operation of the invention, what I desire to secure and hole.

3. A pressure compensator for presses name this 1st obtain by Letters Patent is: g Y

1. A pressure. compensator constructed as a part of a toggle used to swing a press lever, comprising a base attachable ,to a

toggle part; a pressure block attachable 'to the aforesaid press lever; an adjustable stem threaded intoohe of the aforesaidparts to vary the distance between v the base and block; a compression spring hearing at one end on the base; a cap bearing on the opposite end of the spring; and adjusting screws mountednn the pressure block and bearing against the cap to vary the compression of the spring.

2. A pressure compensator for presses comprising a pressure block with a bearing hole to pivotally mount the block on a press part, said block having another bearing hole formed longitudinally therethru and passing at right angles thru' the first named bearing hole, a'spring base, a spring confined between the base and block, a spring cap disposed between the block and spring end, spring adjusting screws cooperating with the block and cap to increase or decrease the spring mpression, and an adjusting screw coopcrating with the block and base to vary, the

overall length of the compensatorand-rotatably confined within the second bearing comprising a pressure block, a sleeve formed thereon, a spring base, a' compression spring disposed on the sleeve and having one end supported on the spring base, a spring cap slidably confined on the sleeve and bearing against the other end of the spring, a screw,

means for adjusting the position of the spring cap in relation to the block toadjust the spring compression, and an adjustrng stem guided in the sleeve and CODIIBCtGdrWIth the spring base and block to vary the overall length of the compensator.

4. A pressure compensator-andequalizer comprising a block, two independent screw.

and block, and a spring cap resting on one I end of the spring and movable up and down against the spring under the action of the other screw means to adjust the spring com pre'ssion. In testimony whereof I hereunto aflix my day of October, 1920.
